2. Description of the Related Art A wire harness mounted on an automobile or the like is once constructed as a plurality of sub-harnesses divided according to the functions of electronic devices and the like, and these sub-harnesses are obtained by being assembled with each other. . For this reason, the connection of the electric wires between the sub-harnesses becomes complicated, and the workability at the time of assembly tends to be deteriorated. In the worst case, the quality may not be stable.

In order to facilitate the connection between the electric wires, the applicant of the present invention has a plate-shaped insulator and a press-fit terminal mounted on the insulator, and the plate-shaped insulator is provided. Proposed a plate connector obtained by laminating a plurality of insulators. The plate-shaped insulator is made of a synthetic resin. The plate-shaped insulator includes a flat bottom wall, a plurality of partitions erected from the bottom wall, and a wire fixing portion.

[0004] A plurality of partition walls are arranged in parallel with each other and at equal intervals. The wire accommodating groove is formed so as to be surrounded by an adjacent partition wall and a bottom wall. The wire accommodating grooves are juxtaposed along the direction in which the partition walls are juxtaposed. The wire receiving grooves are parallel to each other. The wire accommodating groove accommodates at least an electric wire connecting portion of the press contact terminal, which will be described later, and an electric wire pressed into the electric wire accommodating portion.

The wire fixing portions prevent the wires housed in the respective wire housing grooves from coming off. The wire fixing portion includes a locking claw standing upright from an edge that is spaced along the width direction of the wire housing groove, and an engaging member standing upright from the bottom wall. Two locking claws are provided corresponding to the respective wire receiving grooves. The engaging member can be engaged between the locking claws arranged in the adjacent wire accommodating grooves.

When the engaging members are not engaged, the locking claws arranged on the edge of one wire accommodating groove are elastically deformable in a direction of coming and coming from each other. These locking claws allow the electric wire to enter the wire accommodating groove and to escape from the wire accommodating groove when the engaging member is not engaged. Further, when the engaging members engage with each other, the locking claws cannot contact or separate from each other, and prevent the electric wires from coming out of the electric wire receiving grooves.

[0007] The press contact terminal is formed by bending a sheet metal. The press-connecting terminal includes an electric wire connection portion connected to the electric wire, and a cylindrical electric contact portion connected to the electric wire connection portion. The electric wire connection portion includes a pair of press contact blades that press against the electric wire and face each other. A strip-shaped connection bar having conductivity is inserted into the electrical contact portion. The insulation displacement terminal
The electric wire connection part and the electric contact part are arranged at positions where the planar shape is L-shaped. The insulation displacement terminal is mounted on the bottom wall of the plate-shaped insulator.

In the plate-shaped insulator, the insulation displacement terminals are arranged on the bottom wall in two directions, that is, in the longitudinal direction of the wire housing grooves and in the direction in which the wire housing grooves are arranged side by side. That is, the plate-shaped insulator arranges the press contact terminals on the bottom wall in a two-dimensional matrix. A plurality of plate-shaped insulators in which the press-contact terminals are arranged in a two-dimensional matrix are stacked, and the connection bar is inserted into a desired one of the overlapping electrical contact portions to obtain a plate connector.

As described above, in the plate connector, the press contact terminal for press contact with the electric wire is arranged at a desired position on the bottom wall of the plate-shaped insulator, and the connection bar is inserted into a desired electric contact portion. The wires are connected to each other according to a predetermined pattern.

[0010]

When assembling the above-described plate connector, first, a press contact terminal is attached to a desired position of each plate-shaped insulator.

The electric wire is fixed by engaging the engaging member of the electric wire fixing portion between the locking claws. After that, a plate-shaped insulator is laminated.

If the engaging member is not engaged with the locking claw before laminating the plate-shaped insulator, if the electric wire is pulled out or the electric wire is pulled after the plate connector is assembled, the covering portion will be a press-contact blade. Could be removed (so-called peeling). In this way, if you do not fix the wire at the wire fixing part,
The quality and yield of the plate connector may be reduced.

For this reason, before laminating the plate-shaped insulator, it was necessary to confirm whether the engaging member was securely engaged between the locking claws. However, in the above-described wire fixing portion of the plate-shaped insulator, since the engaging member is erected from the bottom wall, it is determined whether or not the engaging member is engaged between the locking claws. It was difficult to do.
That is, it was difficult to securely fix the electric wire.

When the electric wire 4 is inserted into the electric wire accommodation groove 61, the electric wire 4 is pressed into the electric wire fixing portion 70 between the locking claws 71 arranged on both edges of one electric wire accommodation groove 61.

At this time, first, the electric wire 4 is
As shown in (5), the locking claw 71 comes into contact with the claw body 71a.
Further, when the electric wire 4 is pressed into the space between the claw main bodies 71a, the locking claws 71 have an increased interval between them as shown in FIG. 10B against the elastic restoring force.

Further, when the electric wire 4 is pressed into the electric wire accommodating groove 61, the electric wire 4 is placed on the bottom wall 63a.
As shown in FIG. 10C, the locking claw 71 is displaced by the elastic restoring force so as to lock the electric wire 4. Electric wire 4
Is prevented from slipping out of the wire housing groove 61 by the locking claw 71.

Then, the engaging member 72 of the wire fixing portion 70
Is rotationally displaced from the allowable position shown in FIG. 8 around the one end 72a along the arrow K in FIG. 8 against the elastic restoring force. Then, as shown in FIG.
The engagement concave portion 77 of the rectangular parallelepiped portion 76 engages with b, and is displaced to the regulation position.

As described above, the engaging member 72 is elastically deformed against the elastic restoring force and is engaged with the engaging projection 71b. Thus, the engaging member 72 is engaged with the engaging projection 71b of the locking claw 71, and the electric wire fixing portion 70 fixes the electric wire 4 so as not to come off from the electric wire receiving groove 61. In this state, as shown in FIG.
2 are stacked parallel to each other and at intervals.

Then, the press contact plates 60 are brought close to each other, and the locking projections and the locking receiving projections are locked and fixed to each other. In the press contact plate 60, the connection bar 80 is inserted into the predetermined hole and the electric contact portion 52, and forms the laminated plate connector 1 as shown in FIG.

The laminated plate connector 1 has a position where the JB press contact terminal 50 is disposed on the bottom wall 63a and a connection bar 80.
By selecting a position for inserting the wire, the electric wire 4 to be pressed against the JB press-connecting terminal 50 is connected according to a predetermined pattern. Further, the laminated plate connector 1 is housed in an electric connection box in which a relay, a fuse or the like is mounted, and connects the electric wire 4 to the above-described relay or fuse according to a predetermined pattern.

According to the above-described structure, the piece 81 is accommodated in the plate body 62 from the front wall 69, that is, the end 61b, when the engaging member 72 is in the regulating position, as shown in FIG. On the other hand, the piece 81 has an engagement member
8, the front wall 69, that is, the end 61b passes through the through hole 69b as shown in FIG.
Protrude more outward.

For this reason, the piece 81 makes it possible to determine whether or not the engaging member 72 is engaged with the engaging projection 71b.
That is, the piece 81 makes it possible to determine whether the wire fixing portion 70 is located at the allowable position or the restriction position.

For this reason, according to the present embodiment, the worker assembling the laminated plate connector 1 requires the engaging member 7.
It can be easily determined whether or not 2 is engaged with the engagement protrusion 71b. Therefore, as shown in FIG. 2, before stacking the press contact plates 60, the engagement members 72 that are not engaged with the engagement protrusions 71b can be securely engaged.

For this reason, the locking claws 71 of the wire fixing portion 70
Can be reliably maintained at the regulation position, and the electric wire 4 can be securely fixed in the electric wire accommodating groove 61. Therefore, a decrease in the yield of the laminated plate connector 1 can be prevented.

[0075]

As described above, according to the first aspect of the present invention, a worker or the like assembling a plate connector requires:
By the determining means, it is possible to determine whether the wire fixing portion is located at one of the restriction position and the allowable position. For this reason,
Before laminating the plate-shaped insulators, the wire fixing portion at the allowable position can be displaced to the regulation position. Therefore, since the electric wire fixing portion is displaced to the regulation position and the electric wire can be securely fixed, a decrease in the yield of the plate connector can be prevented.

According to the second aspect of the present invention, the piece as the discriminating means projects outward from the outer edge of the plate body at the allowable position, and does not project from the outer edge at the restricting position. Therefore, it is possible to reliably determine whether or not the engaging member is engaged between the locking claws. Therefore, before the plate-shaped insulator is laminated, the engaging member can be reliably engaged between the locking claws. Therefore, since the engaging member can be engaged between the locking claws, the electric wire can be securely fixed, and the yield of the plate connector can be more reliably prevented from lowering.

According to the third aspect of the present invention, the piece projects outwardly through the through hole provided in the outer wall at the allowable position. Therefore, the piece reliably projects outward from the outer edge of the plate body at the allowable position, and does not project at the regulation position. Therefore, it is possible to reliably determine whether or not the engaging member is engaged between the locking claws. Therefore, before the plate-shaped insulator is laminated, the engagement member can be more reliably engaged between the locking claws. Therefore, since the engaging member can be engaged between the locking claws, a decrease in the yield of the plate connector can be more reliably prevented.
